  Search of antitubercular activities in tetrahydroacridines: Synthesis and biological evaluation

  摘要：

  A series of 9-substituted tetrahydroacridines were synthesized by nucleophilic substitution of chloro group with different nucleophiles in 9-chlorotetrahydroacridine (2). The latter could be obtained by POCl3 mediated cyclization of the intermediate enamine, which in turn, was prepared by acid catalyzed condensation of anthranilic acid and cyclohexanone. Most of the compounds on antitubercular evaluation against M. tuberculosis H37 Rv and H37 Ra strains exhibited potent activities with MIC 6.125-0.78 mu g/mL comparable to the standard drugs.

  Linking two tacrine molecules results in a tremendous increase of activity against Plasmodia in comparison to the monomer. This finding prompted the synthesis of a library of monomeric and dimeric tacrine derivatives in order to derive structure–activity relationships. The most active compounds towards chloroquine sensitive Plasmodium strain 3D7 and chloroquine resistant strain Dd2 show IC50 values

  与单体相比，连接两个他克林分子导致抗疟原虫的活性大大增加。这一发现促进了单体和二聚他克林衍生物库的合成，以推导结构-活性关系。对氯喹敏感的疟原虫菌株3D7和对氯喹耐药的菌株Dd2最具活性的化合物在纳摩尔浓度范围内显示IC 50值，细胞毒性低，并靶向半胱氨酸蛋白酶falcipain-2，这对寄生虫的生长至关重要。

  to the efficient and completely regioselective generation of aromatic CC and CN bonds. The method is simple, rapid, general and inexpensive, and can be performed without the use of dried solvents. Most of the synthetized compounds are new and in many cases the work‐up required only filtration. Furthermore, this is the first example of the use of a Lewis acid as a catalyst for heteroarylation, vinylation

  在催化量的三氯化铟的存在下，对一系列卤化的氮杂环和不同种类的亲核试剂进行聚焦微波辐照可有效且完全区域选择性地生成芳族CC和CN键。该方法简单，快速，通用且廉价，并且可以在不使用干燥溶剂的情况下进行。大多数合成的化合物都是新化合物，在许多情况下，仅需过滤即可进行后处理。此外，这是使用路易斯酸作为催化剂在π缺陷杂环底物上进行杂芳基化，乙烯基化和胺化反应的第一个例子。

  An efficient and economical synthesis of a series of rationally designed novel 9,9′-(alkane-1,ω-diyldiimino)-1,2,3,4-tetrahydroacridines (ω = 7–10) and a second series of new analogues, 9-(ω-phenylalkylamino)-1,2,3,4-tetrahydroacridines (ω = 4–10), is reported. Compounds in the first series are found to be up to 10 000-fold more selective and 1000-fold more potent in reversibly inhibiting rat acetylcholinesterase (AChE) than the monomer, 9-amino-1,2,3,4-tetrahydroacridine (THA). Some members in the latter series (ω = 7–8) are slightly more potent than THA in inhibiting AChE but still more selective. These compounds can serve as (i) important chemical tools to evaluate the role of AChE inhibition by THA, a clinical drug, in treating Alzheimer’s disease, (ii) effective, safer and low-cost insecticides and parasiticides, (iii) potential blockers of the K+ channel and the N-methyl-D-aspartate receptor channel, and perhaps (iv) improved therapeutics for Alzheimer’s disease.

  amination protocol is described for the synthesis of N-alkyltacrines and analogs. The Josiphos ligand CyPFtBu was found to provide optimum yields: 16 examples are given. Compared to the typical high-temperature nucleophilic aromatic substitution (NAS) routes, Pd-catalyzed aminations proceed at significantly lower reaction temperatures, and enable the synthesis of otherwise inaccessible products.
